* The harrow cylinder in "cross -;section may be either circular, hexagonahior. other" .75 1 platform is aspring-supportf,"towhicl1is at- I v contour and is journaljed in the bearings B.-

"The, cylinder may suitahl''ylbeiqriadeof iron. )pipin'g and is provided with"harrowsteethl;

setqin a rowand each tooth; transversely of the axis of the'cylin'derp Oollarsjgare prog vided'to'prevent endmotionofthe cylinder," a V the collars bea'ring'aga'inst'jthesides'of the 7 members A; .The'cylinderlis also'provided ,With a rocking armfJ, extending-:upwardly from the'central portion thereof,;and thearm is connected with the lever E'hy a rod i,wh ich, although for convenience is shown rather as 3, .a :pullrodyis in pract'icega stiff unyielding push-rod; It will be apparentthattwo or I06 more barrow-cylinders and s'etsof teeth may lee-employed, an connected togethenandalso any desired number of planks C may be employed in construction, depending upon the size of implement contemplated.

In practical use the draft-team may be hitched to the clevises e, one or two animals to each clevis, and the harrow-teeth set either in a vertical plane or in an inclined plane, as may be desired, by movement of the lever F and its latching devices. In some cases it may be desired to work with the points of the teeth forward of the cylinder H, so that light trash will slide up the teeth and fall rearward over their upper ends to the ground,

and in some cases the teeth-points may draw back of the cylinder, and should some trash adhere to the teeth it may be dislodged by manipulation of the controlling-lever, as will be apparent. When moving, the forward edges of the planks C will cut or break large lumps of earth and the lower faces will pass over and crush and pulverize the remainder, as well as drag the earth and fill up uneven places, while the harrow-teeth will loosen the ground-surface suitably to receive the seed. In transporting the implement on roads the teeth-points may be elevated so as to clear the ground.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a drag and harrow-pulverizer com-- bined, the combination of the main frame members each having the journal-bearings and also the recesses therein, the clevis attached to each main frame member, the clodbreaking members having their forward edges in said recesses and separated one from the other, the platform having the narrow rear end and attached to said clod-breaking members between said main frame members, the rocking cylinder journaled in said bearings, the harrow-teeth in said cylinder, and the arm attached to said cylinder adjacent to the narrow rear end of said platform, substantially as set forth.

2. In a drag and harrow-pulverizer combined, the combination of the main frame members having the inclined lower forward faces, the clevises attached to said members independently, the harrow mounted at the rear ends of said main frame members, the clod-breakin g members attached to said main frame members between said harrow and the rear ends of said... lower forward faces, the platform, and the arm attached to the harrow, substantially as set forth.

In a drag and harrow-pnlverizer combined, the combination of the main frame members, the clod-breaking members, the platform, the journaled rocking harrow-cylinder, the arm attached to the rocking cylinder whereby the same maybe locked against movement thereof, the controlling lever mounted on the platform, the connecting-rod, the harrow-teeth extending through said cylinder, and the stop-collars on said cylinder at the sides of said main frame members, substantially as set forth.

4. In a drag and harrow-pulverizer combined, the combination of the main frame members, the clevises at the forward ends of said frame members, the clod-breaking members attached to said frame members, the journal hearings in the rear ends of said frame members, the rocking cylinder mounted in said bearings, the harrow-teeth extending through said cylinder and projecting at each side thereof, the arm secured to said cylinder, the platform on said clod-breaking members, the notched quadrant on said platform, the operating-lever connected to said quadrant, the lever-latch, the latch-trigger, and the push-rod connected to said lever and also to said arm, substantially as set forth.

5. In a drag and harrow-pulverizer combined, the combination of the main frame members, the clod-breaking members, the platform, the journal-bearings in said main frame members, the quadrant on said platform, the controlling-lever, the connectingrod, the rocking harrow-cylinder mounted in said bearings and consisting of the hollow tube having transverse apertures, therein, the teeth driven into the apertures, and the arm attached to said cylinder between two of said teeth and attached to said connectingrod, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
